variable (up to 2.5 Crab)

10 December 2001 --

Weeks 304 and 305 results (2001 November 23 - December 6)

LMC X-3 - is up to ~40 mCrab

These reports of results are sparse at this time due to two reasons.
First, the RXTE S/C and instruments did not conduct observations for
the last 4 days of week 304 because of a S/C operations problem.
Second, the Sun is now affecting observations of Galactic Center
sources.

GX 301-2 - relatively strong and active with intensity up to 100 mCrab
in the daily averages

X1636-536 - very low at ~50 mCrab

XTE J1650-500 - declined to ~330 mCrab

X1745-203 (in NGC 6440) - may have declined in strength (on the basis
of very few observations)

SAX J1750.8-2900 - appears to be weak (< 15 mCrab)

KS 1947+300 - <10 mCrab

24 October 2001 --

record for this source

Week 296 results (2001 September 28 - October 4)

X1246-588 - stronger than usual at ~20 mCrab

XTE J1650-500 - ~380 mCrab

X1745-203 (in NGC 6440) - ~170 mCrab

Cyg X-1 - active mostly in the 0.5 to 1.0 Crab range

Cyg X-3 - at ~100 mCrab in daily averages is much quieter than it has
been for 3 months

Note: Last week's reports of increases in the fluxes of SGR 1806-20,
GS 1826-238, and possibly also SAX J1747-2843 are likely to be
incorrect. These may be attributed to the outburst of X1745-203 and
to an urgent need for the ASM position calibration files to be
updated. The ASM light curves have been corrected for the increase in
intensity of X1745-203 and work is in progress on updating the
calibration.
